Anyone else get alerts from their BGP monitoring system (In my case 
Cyclops) saying Cogent briefly announced some more specific prefixes?

AS path as reported by Cyclops: 7575 46135 174 174

/20s broken into /23s
/23s became /24s

Also saw alerts for one to one (/23 announced has /23)

All alerts had a timestamp of: 2010-11-25 12:01:12 UTC
